Monitoring Large Hydrogen Sulphide Releases:   Why Sensor Recovery Time Is Important  

Hydrogen sulphide (H2S) is a highly toxic gas and among the most common contaminants in crude oil and natural gas. Not surprisingly chemical process and petroleum facilities use H2S gas detection systems to assure personnel are alerted to hazardous gas releases or to detect and avert large releases that could pose a significant hazard to personnel, property, the environment, or public outside the plant perimeter.  To address the likelihood of such hazards, plant operators have a variety of sensor technologies at their disposal to choose from.  Electrochemical sensors, solid state sensors, impregnated paper, and laser based open path detectors are among those methods used to supply early warning and initiate an appropriate automatic protective response.
